>>168112>Enjoy your warped discsMost of the discs I've had to straighten are on hydraulic brake bikes, probably because that's what most people have. Those disks are designed to flex in normal use. I've never had to straighten my mechanical disk rotors.
Enjoy the spray of DOT fluid or mineral oil when you have to pop out the piston with compressed air when your calipers need a rebuild. Sure, put it in a plastic bag first, but that barely contains it. Hydraulics might have some advantages, but longevity between rebuilds is not one of them. The fewer moving parts in hydraulic brakes are immersed in toxic fluid. To me, this is the antithesis of the bicycle, which is supposed to be relatively simple. Bicycles are becoming too high-tech, too much like motorcycles, too many brand-specific special tools.
I've been working on bicycles for 40+ years. Pic related, my first $25 junker that I fixed up myself, because I couldn't afford a new bike or a mechanic. (I took this pic myself, developed the film, souped the print in trays in the bathtub.)
